Intel said it expects first-quarter revenue of $12.7 billion, plus or minus $500 million. Gross margin is expected to be 58%, plus or minus a few hundred basis points. Analysts expect earnings of 39 cents a share on sales of $12.9 billion.

AT&T ( T) said Thursday it would record a $10 billion fourth-quarter charge related to its pension and benefit plans.

The telecommunications giant also warned that high smartphone subsidies will put pressure on its fourth-quarter profit.

"Due to the high subsidies on these devices, we expect a near-term pressure on operating income, margins, and earnings per share in the fourth quarter of 2012," AT&T said, in an 8-K filing with the Securities and Exchange Commission.
